nitraat WRIST-WATCH BRACELET FASTENER.

Application led November,

This invention relates to improvements in wrist watch constructions.

An object of the invention is to provide a wrist watch having on its wrist encircling member a resilient link ldevice ofimproved construction permitting the wrist encircling member to accommodate itself'to the wrist.

Another object of the invention isvto provide an improved fastener construction by which an end of theV wrist encircling member may be attached to the bail of a wrist watch. A further object of the invention 1s to provide a construction in which the fastener and the resilient link are combined upon the same body, permitting chains, ribbons, straps and other devices to be employed as wrist Vencircling members.

l/Vith the foregoing and other objects in view which will be made manifest in the following detailed description and specifically pointed ont in the appended claims,

- reference is had to the accompanying drawings for an illustrative embodiment of the invention, wherein:

Referring to the accompanyingdrawings wherein similar reference characters designate similar parts throughout, the wrist watch is indicated at W, and is provided withl a wrist encircling member 10 which may be of. any flexible construction, such as ribbon, chain, mesh, strap or their equivalents. Adjacent each end of the wrist encircling member 10 there is secured a part gen- 12, 1925. Serial No. 68,589.

Fics.

erally designated at 11, so that'each end of l the wrist encircling member can be detachably fastened to a bail B upon the wrist watch W. Preferably there are two of the parts 1 1 used, one on each end of the wrist encircling member 10, so as to present the symmetrical appearance and also to permit` Veither end of the wrist encircling member to be detached from the watch.

The part 11 is constructed in the following mannen A front wall 12 is provided from the edges of which extend end walls 13 and 14. Back walls 15 and 16 extend toward each other .but have their adjacent Y disposed between the front wall 12 and theV edges of the intermediate walls 17 and `18. On the front wall 19 there are formed end walls 21 and 22 which are connected by a back wall 23. r[he end walls 21 and 22 and the back wall 23 are slidable between the iiitermediate walls 17 and'18. A coil spring` 24 is positioned between the end walls 21 and 22 and a pin or rivet 25 passes through the side walls 13 and 14 and the intermediate walls 1-7 and 18 and is positioned between Y the end wall 21 and the end of the coil spring 24. This provides the resilient link construction for the wrist encircling member 10. As clearly shown in Fig. 6 the front wall 19 can-be withdrawn from between the front wall 12 and the intermediate walls 17 and 18 by compressing the spring 24. This spring is compressed because of its engagement with the pin or rivet 25, and by this con-1 struction it urges the front wall 19 into its normal position behind the` front wall 12. The back walls 15 and 16 are joined Aas indicated at`26 and the back wall 26 extends beyond the ends of the end walls 13 and 14. It has its` end edgebent yas indicated at 27 to form a hook adapted to receive one of the,

bails B.

between the side walls 13 and 14, rigidlll ly formed with the mentioned end of the guard are two tubular members 29 forming a tubular housing which is arranged between the side walls 13 and 14 and which is rigid with the guard E28. Pintles 30 are disposed in the ends of the tubular housing so formed and extend through apertures in the side walls 13 and 14e, thus pivotally connecting the sides of the guard 2S to the side walls 13 and la. A coil spring 31 is disposed within the tubular housing and urges the pintles 30 toward their respective side walls, bu-tpermit's 'the pintles to' be pressed inwardly against the action of the spring, The endsof the pintles 30 are preferably provided withv caps 32' whiclrlimit their in- Award movement through the sidewalls 13 and 1.4i: lneach of the tubular members 29 thereA are formed slotsV and each pintle carries-anangular arm S4 which is slidable in its respective slot 33. The end of each arin Betis capable of enga-ging upon the edge of` its respective side wall 13 or 1st, as' the case may' be, asshjown in Fig. 7, or is adapted" to enter an'aperture such as is indicated at 3 5 in'tsl respective side wall;

Inthe position shown in liig. 7 it will be readily appreciated that when the arms 34C engage upon theedges of their respective side walls, they keep or lock the' guard 28 in open position, that is, where it is disengage'd from the hook 27. lVhile in such position the hook maybe caused to be slipped over a bail B. After it has been positioned upon the bail, theguard 28 can be pressed toward the hook; and because of the beveled natureiof the arms34,as shown in Fig. 5, the'pintlesA willl slide inwardly against the action of the spring 31 and when the guard 28 engages the hook, as shown in Fig, 4;, these angular arms 34 will enter the apertures 35, thus lockingthe guard in engage ment with the hook 2T, and preventing-the bail from slipping' out of thehoolc. In order to open the'A fastener so prow'fided, the

pintles are merely pressedtoward'each other, causingthe arms Sel to be withdrawn from' within the apertures' 55, and'in this manner the guard 28 can be swung into the open' position as shown in Fig. 7, ,and the pint-les allowedvto be expanded so that the arms will engage upon the edges of the side walls 13 and 14.; thus locking the guard in its open position.

From the above described construction itl willbe readily appreciatedthatv an improved resilient link and' fastener is providedV for wrist watch encircling members which is neat and attractive in appearance and which has many advantages. It will beV noted that whenthe frontr wall 19 is withdrawn from behind the front Vwall 12, it presents a sub stantially continuous appearance.

It will be understood that various changes in the detail of construction may be made without departing` from the spirit or scope of the invention as deined by the appended claims.
